- 继上次抬头屏幕增强（MIGO 抬头屏幕自定义字段增强示例），本文章演示行项目增强示例
- 实现思路参考标准 MB_MIGO_BADI 增强示例类：CL_EXM_IM_MB_MIGO_BADI
1.创建增强数据表 & 增强结构
- 创建增强数据存储表
- 创建增强数据结构
- 创建增强数据表类型结构
2.创建增强屏幕
- 新建Function Group，定义全局变量（本章继续使用抬头增强的Function Group）
- 创建数据处理函数
- ZMM_I_GET_DATA（行项目：从屏幕获取数据）
- ZMM_I_SET_DATA（行项目：输出数据到屏幕）
- ZMM_UPDATE_DATA（抬头/行项目：更新数据到数据库 ）
- ZMM_SET_GOACTION（抬头/行项目：设置屏幕Action Code）
3.创建行项目增强子屏幕9002
- 创建屏幕
- 创建屏幕字段
- 创建PBO处理逻辑
4.创建BADI实施
- SE19 创建BADI实施
- 新增实施类属性
